Much was made leading up to the May 15 primary about it being a closed primary. Many worried that it would turn away voters and result in very few registered voters actually taking part. If the preliminary low primary vote numbers are any indication, the closed primary will be a discussion point for the GOP.

As a result of the turnout, according to the Idaho Statesman, Gov. Butch Otter said the issue is likely to be raised at the GOP convention. Otter said he is very disappointed in the turnout, which looks to be around 25 percent of registered voters when the final numbers are released on May 30.
